  • METHOD OF HEAT TREATMENT AND/OR INSPECTION OF FUNCTIONAL MECHANICAL PROPERTIES, PARTICULARLY TRANSFORMATION STRAIN AND/OR STRENGTH, OF SHAPE MEMORY ALLOY FILAMENTS AND APPARATUS FOR THE APPLICATION OF THIS METHOD
    Publication number: 20120018413
    Abstract: A method of heat treatment and/or inspection of functional mechanical properties, particularly transformation strain and/or strength, of shape memory alloy filaments and apparatus for the application of this method. This invention introduces a method and equipment for nonconventional thermo-electro-mechanical treatment of continuous and discontinuous SMA filaments, particularly NiTi, allowing for setting their functional mechanical properties, particularly transformation strain and/or strength, as required by the user. Heat treatment of continuous SMA filaments is realized on an apparatus consisting of respooling system with driving units for feeding and taking spools and at least two electrical contacts allowing conductive for electrical contact of the respooled filament and electric current source.
